standard by International Organization for Standardization, 04/01/2019
ISO 24598:2019 specifies requirements for classification of solid wire electrodes, tubular cored electrodes and electrode/flux combinations (all-weld metal deposits) for submerged arc welding of creep resisting and low-alloy elevated-temperature application steels. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical composition.
This document is a combined specification providing a classification system based on either:
the chemical composition of the solid wire electrode and all-weld metal deposit; or
the tensile strength of the all-weld metal deposit and the chemical composition of the solid wire electrode and all-weld metal deposit obtained with the electrode/flux combination.
Clauses, subclauses and tables which carry the suffix letter A are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified in accordance with the system based upon chemical composition. Clauses, subclauses and tables which carry the suffix letter B are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified in accordance with the system based upon the tensile strength of all-weld metal deposits and the chemical composition of solid wire electrodes and all-weld metal deposits. Clauses, subclauses and tables which do not have either the suffix letter A or the suffix letter B are applicable to all solid wire electrodes, tubular cored electrodes and electrode/flux combinations classified under this document.
